Halpin, St. Paul, Minn., assignor to Minnesota Mining & Manufacturing Company, St. Paul, Minn., a corporation of Delaware Application November 23, 1932, Serial No. 644,064 In Great Britain August 9, 1932 10 Claims.

The invention relates broadly to a device for containing and dispensing rolls of ribbon-like material, and more particularly to a device for retaining and dispensing rolls of adhesive tape of a nature such that temporary adhesion between the successive layers of the tape in the roll will normally prevent the tape from unrolling except by the act of the user.

This invention as represented by its several forms finds particular utility for holding and dispensing pressure sensitive adhesive tapes, such, for example, as those disclosed in the patent to Drew 1,760,820, May 27, 1930 and wherein by virtue of the tacky nature of the adhesive layer and the structure of the container, the tape may be dispensed directly from the container onto the surface to which it is to be applied.

The principal objects and advantages of this invention reside in the provision of a device for containing and dispensing a roll of ribbon-like material, which is simple and economical of construction, of such a' nature as to readily allow the removal or insertion of a roll of the ribbonlike material, and provided with a means for 25 severing any desired length of such material from the roll; the provision of an improved container for pressure sensitive tape having severing means forming a part of the container; the provision of an improved container of the character referred to wherein the tape roll is available from without the container so that the rotation of the roll of tape may be arrested as desired to facilitate severing; the provision of an improved container for pressure sensitive tape which is of such economical construction as to permit the container to be marketed with roll of tape so as to make convenient the use of the tape; and the provision of an improved container for pressure sensitive tape which will insure efiicient and accurate dispensing of the tape and thus avoid waste.

The invention has as further objects the provision of a container for tapes by which the tape may be dispensed directly from the roll onto a surface to which it is to be applied and in which said container is provided with a severing blade whereby the tape dispensed may be conveniently severed from the roll, at the same time leaving available a part of the roll so that it is presented convenient of access for dispensing additional portions of the tape.

While the various forms of this device as shown and described are designed particularly for use for containing and dispensing rolls of pressure 55 sensitive adhesive tape, the device may be used with other tapes, and therefore finds a wide field of utility in connection with analogous materials.

The foregoing and such further objects and advantages as may appear or be pointed out as this description proceeds are attained in the 5 structural embodiments illustrated in the accompanying drawings, in which:

Figure 1 is a view of the flat stamping used in certain forms of this device.

FigureZ is a side elevation of one form of the device completely formed from the blanleshown in Figure 1.

Figure 3 is an edge elevation.

Figure 4 is a view similar to Figure 2 of another form of the device with a portion cut away to show the spool of tape in position and a method of using the device.

Figures 5 and 6 are side elevation and edge views respectivelyof a further modified form of the device formed from a modified blank similar to that shown in Figure 1.

Figures 7 and 8 are side elevation and edge views respectively of a further form of the device, and

Figures 9 and 10 show the stampings from which the form shown in Figures 7 and 8 is made.

Referring now to the drawings and first more particularly to Figures 1 to 3 inclusive, one form of the device is made from the single sheet metal stamping l0, comprising two disc-like side portions H and I2 connected by a bridge portion 13 forming an abutment, which is provided with a laterally extended portion l4 having a serrated edge 15. This blank is formed over a suitable die so that the sides II and I2 are bent along the dotted lines Ha and H41, respectively, so that they are held in parallel spaced relationship by the bridge portion l3. The sides II and I! possess a desired degree of resiliency for a purpose which will hereinafter appear.

The annular portions of the sides H and [2 inside of the dotted lines "5a and Ila, respectively, are bent to form the inwardly projecting circular flanges l5 and IT respectively which act as spindles for the roll of tape l8 which is wound on a hollow core l9, which may be conveniently a short section of cardboard tube. The portion I4 is bent along the dotted line a to an angular relation with the bridge portion l3 as shown, thus placing the serrated edge I5 in a convenient position for use in severing any desired length of the tape which has been removed from the roll. 1

After the respective parts are in their. desire relation with each other the areas indicated by 56 vided on the sides II and I2 to the dotted lines 20a and Ma are formed into the ribs 20 and 2| respectively, which act as reinforcing means to impart a certain degree of rigidity and to hold the portions of the device in the desired relative positions.

The device made as above described provides a simple and convenient structure in which the roll l8 of adhesive material may readily be inserted or removed by springing apart the side members II and I2. When thus inserted it is held in place and yet is revoluble on the spindles l6 and I1, and the tape may be readily removed in any desired length by holding the device between the thumb and forefinger of one hand and pulling outwardly on the edge of the tape. The rotation of the roll on the spindles may be readily controlled by the pressure of the thumb or flnger on the side walls acting as a brake on the roll itself, and the tape may be severed at any desired point by bending it up along the portion l4 and tearing off along the serrated edge l5. This will leave the short portion of the tape which extends along the portion l4 loose on the roll to serve as a tab for unrolling the next section.

A modified form of the device is shown in Figure 4. This is made from the same stamping as shown in Figure 1 and is formed in the same way as the device shown in Figures 2 and 3 with the exception that the extended portion I4 is bent in the form of an are as shown at |4b. In Figure 4 a portion of the wall II -is shown cut away to show a roll of pressure-sensitive tape in position. The portion I4!) is so bent and curved P with relation to the side walls H and I2 that when these are moved along, or slightly raised from a surface, S. on which it is desired to apply the tape, the bent portion |4b may be used as an applicator to press the tape directly in place, as it is dispensed from the roll, andthe tape may be severed at any desired point bytipping up the holder to bring the serrated edge IS in contact with the tape. In Figure 4 the cutaway portion shows the roll of tape in position and the way in which it is applied to the surface, S. It is obvious that the. form of the device as Figure 4 can also be used in the manner described above for the form shown in Figures 2 and 3, and also that to a limited extent the portion 14 of the form shown in Figures 2 and 3 may serve as an applicator similar to portion Mb 01' the form shown in Figure 4. 4

A further modified form of the device is shown in'Figures 5 and 6 where the portion l4 of the blank shown in Figure 1 is dispensed with and the serrated cutting edge |5b is formed on the side of the bridge member 3 along the line |4a. In'this form also, additional material is proallow the forming of rolled circumferential beads around the outer circumference of these side members as shown at llb and H12.

This form of the device is used in the same manner as described above for the form shown in Figures 2 and 3. g

It is readily seen that the rolled edges llb and I2?) as shown in the form of the device in Figures 5 and 6 may also be provided in the-forms shown in Figures 2, 3 and 4 if desired.

Referring now to Figures 7 to 10 inclusive which show a form of the device consisting of two separable cooperating members 30 and 3| formed from blanks as shown in Figures 9 and 10, respectively, the member 3|! being formed from the blank shown in FigureQ, over a suitable die which shown in forms a body portion 32, which may be upset between the lines 32a and 32b to form the annular crowned portion 320 as shown. The annular portion inside of line 32b is bent to form the inwardly projecting circular flange 33. The portions 34, 35 and 36 are bent along the lines 34a,

35a and 32a to form the side members as shown in Figures 7 and 8.

The member 3| is formed from the blank shown in Figure 10 having the body portion 31 with the annular crowned portion 310, the inwardly projecting circular flange 38 and side members 33. 40. and 4| formed in the same manner as described above. A proj ecting portion on side member 39 is bent along line 42a to form an abutment adjacent to the outlet, and aiiording the guide and applicator blade 42 and is provided with a serrated cutting edge 43 at the outer.

end.

When these members 30 and 3| are placed together to form the device as shown in Figures 7 and 8 the side members 33, 40 and 4| of members 3| fit inside of side members 34, 35 and 36 of member 30 respectively and form apertures 48 on either side of members 36 and 4|. The inherent resiliency of these members sets up a frictional contact between the side portions thereby holding the two members together. The inwardly directed flanges 33 and 38 are thus oppositely disposed to each other and form a spindle for the core 44 of a roll, 45, of adhesive tape or other ribbon-like material. The core 44 is conveniently oi cardboardand of a length such as to contact with the flanges 33 and 38 and be freely revoluble about them;

The eo-operating members 30 and 3| are so constructed that the sides 35 and 40 are shorter than sides 34 and 33 and thus when struck up into angular relationship with the members 30 and 3| a slot 46 is afforded adjacent to the apex 41 of the container.

The tape when unrolled is dispensed through the slot 46 along the guide 42 and may be severed at any desired point by the serrated edge 43.

It will be observed that when the members 30 and 3| are properly assembled the guide 42 forms a continuation of the plane of the outer surface of the side 35. Thus if desired this guide may be used as an applicator for applying pressure sensitive adhesive tape directly onto a surface as desired, thus eliminating extra handling, and at the same time leaving one of the users hands free to hold two or more objects in desired position for receiving the tape.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is: v
